System.Net.HttpListenerException: An operation was attempted on a nonexistent network connection

[dherron]

For the last few days, Ive recieved this error which causes the service to stop. The error occurs about 100 times per second each time this happens.

I currently have it set to scan 25 at once which has ran fine all day for the last few weeks however recenlty, its failing once per day after approx 700 scans were made.

Im running it from a P3 and the CPU is at 100% all the time - Its very upset with me. Im moving it to a better server but the P3 was used for testing in our environment - is it possible the machine just cant keep up with the requests? According to the error - it almost seems that the network connection to the server is lost?

I did not have this problem when I only scanned 10 at once.

It also seems to happen while Im refreshing the service status page a few times a minute - while watching for new computers to be added to the In Queue list. I do this many times per day - but again after about 700 comptuers have been processed, it doesnt seem to like it.

Any insight you can provide is appreciated.
Thanks!

That's why you can tweak it, just set it back to 10.
